Specific heat (Cp) of Apiezon N grease (1 to 108 K) and calorimetry: Cp of copper below 30 K
Abstract
Heat capacity (Cp) data for Apiezon N grease from 1 to 108 K are compared with previous results for this grease and for Apiezon T, with good agreement. Addenda results for a calorimeter in which Apiezon N grease is used for thermal contact between the tray and a sample suggest that a thin film of this grease has an appreciably larger Cp, below 4 K, than bulk grease. For high accuracy experiments using Apiezon N grease, care should be taken in the calculation of addenda Cp’s from bare tray data and the Cp for bulk grease. During these measurements, Cp data for a high purity electron beam melted copper sample were found to be in excellent agreement from 1 to 30 K (±0.2%) with previous measurements [Holste, Cetas, and Swenson, Rev. Sci. Instrum. 43, 670 (1972)] on a different sample using a quite different calorimeter.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
